Citra
A Nintendo 3DS Emulator
Citra is an experimental open-source Nintendo 3DS emulator/debugger written in C++. It is written with portability in mind, with builds actively maintained for Windows, Linux and macOS. Citra emulates a subset of 3DS hardware and therefore is useful for running/debugging homebrew applications, and it is also able to run many commercial games! Some of these do not run at a playable state, but we are working every day to advance the project forward. (Playable here means compatibility of at least "Okay" on our game compatibility list.) Citra is licensed under the GPLv2 (or any later version). Refer to the license.txt file included. Please read the FAQ before getting started with the project. If you want to contribute please take a look at the Contributor's Guide and Developer Information. You should also contact any of the developers in the forum in order to know about the current state of the emulator because the TODO list isn't maintained anymore. -

Xenia Canary
Xbox 360 Emulator Research Project
Xenia Canary is an experimental fork of the Xenia Xbox 360 emulator that moves faster than the mainline project to trial bleeding-edge improvements. It focuses on game compatibility and performance by iterating quickly on GPU and CPU emulation paths, shader translation, and timing correctness. Canary builds are where risky optimizations, new backends, and rewrites land first so they can be tested by a wider community before stabilizing. The project emphasizes pragmatism: make more titles boot and run with fewer glitches, even if it means carrying experiments that later get refined or rolled back. It also prioritizes developer ergonomics with logging options, debug overlays, and issue templates that help narrow down regressions. While aimed at enthusiasts and testers, it remains a valuable way for end users to play otherwise inaccessible 360 titles on PC when the mainline is lagging behind those fixes. -

MAME
MAME is a multi-purpose emulation framework
MAME's purpose is to preserve decades of software history. As electronic technology continues to rush forward, MAME prevents this important "vintage" software from being lost and forgotten. This is achieved by documenting the hardware and how it functions. The source code to MAME serves as this documentation. The fact that the software is usable serves primarily to validate the accuracy of the documentation (how else can you prove that you have recreated the hardware faithfully?). Over time, MAME (originally stood for Multiple Arcade Machine Emulator) absorbed the sister-project MESS (Multi Emulator Super System), so MAME now documents a wide variety of (mostly vintage) computers, video game consoles and calculators, in addition to the arcade video games that were its initial focus. The MAME project as a whole is distributed under the terms of the GNU General Public License, 2 (GPL-2.0), since it contains code made available under multiple GPL-compatible licenses. -

emuiibo
Virtual amiibo (amiibo emulation) system for Nintendo Switch
Virtual amiibo (amiibo emulation) system for Nintendo Switch. A virtual amiibo is detected by emuiibo based on two aspects: a amiibo.json and a amiibo.flag file must exist inside the virtual amiibo's folder mentioned above. If (for whatever reason) you would like to disable a virtual amiibo from being recognised by emuiibo, just remove the flag file, and create it again to enable it. While old emuiibo formats are supported and converted to the current format (see above), it is strongly suggested to, unless bin dumps might be indispensable, emuiigen be used, our PC utility designed to create and edit virtual amiibos. -

Proton-GE-Custom
Compatibility tool for Steam Play based on Wine
Proton-GE-Custom is an unofficial compatibility tool for Steam Play that builds on Valve’s Proton and Wine codebases to provide additional patches, fixes, and enhancements for running Windows games on Linux systems through Steam, particularly on Steam Deck and other Linux gaming platforms. Unlike the official Proton builds, this custom fork includes community-developed patches such as media foundation support, raw input improvements, AMD and Nvidia optimizations, and broader compatibility tweaks that help certain games launch and run more reliably or with better performance. It also incorporates a “protonfixes” system that applies per-game adjustments automatically, enabling environment variables or workarounds without manual user intervention. Because it packages its own versions of DXVK, VKD3D, and other components, this tool can resolve glitches or missing features in titles that struggle under standard Proton builds. -

DuckStation
Fast PlayStation 1 emulator for x86-64/AArch32/AArch64
DuckStation is an simulator/emulator of the Sony PlayStation(TM) console, focusing on playability, speed, and long-term maintainability. The goal is to be as accurate as possible while maintaining performance suitable for low-end devices. "Hack" options are discouraged, the default configuration should support all playable games with only some of the enhancements having compatibility issues. A "BIOS" ROM image is required to to start the emulator and to play games. You can use an image from any hardware version or region, although mismatching game regions and BIOS regions may have compatibility issues. A ROM image is not provided with the emulator for legal reasons, you should dump this from your own console using Caetla or other means. DuckStation features a fully-featured frontend built using Qt, as well as a fullscreen/TV UI based on Dear ImGui. -

Xenia
Xbox 360 Emulator Research Project
Xenia is an open-source experimental emulator for the Xbox 360 that aims to let users run Xbox 360 games on Windows and other platforms by reverse-engineering the console’s hardware and firmware behavior in software. It implements the 360’s CPU (Xenon), GPU (including Direct3D shader logic), and system libraries to translate Xbox instructions into equivalent host machine operations, enabling many titles to launch and in some cases play at improved frame rates compared with the original hardware. Because Xbox 360 games use custom hardware features and proprietary APIs, Xenia developers have progressively mapped and translated these into PC-friendly code while balancing performance and accuracy, and the project includes compatibility tracking so users can see what games work and how well. Although not all titles are supported and some still suffer graphical or audio issues, the emulator continues to evolve with community contributions and experimental support for Vulkan and Direct3D. -
